[DrJava] Update lib for Debugger!

[Charles R. <cr...@ri...>]

Hey everyone--
   We've committed an early version of the integrated JSwat debugger, 
though it's still commented out for now (just so our group can share our 
work on it).  In order to compile, you'll need to also update your lib 
directory to get the jswat.jar, and then put it on your classpath.  Note 
that you do not need JSwat on your classpath to _run_ DrJava, so users 
won't need it (and we won't include it in drjava.jar yet).

Note that you'll need to use "cvs update" in the lib directory, since 
there is no ant build.xml file there.
